Meshing of Point Clouds from a 3Dlaser scanner

Question

Is there any package/software which can do Meshing of Point Clouds in real time?

What is the data structure used to represent 3D Point Clouds ?

Answer 1

MeshLab is a great one for meshing point clouds.

Look under Filters > Re-meshing, simplification and reconstruction. Ball Pivoting Surface Reconstruction and Poisson Reconstruction are good ones.

Here you can find a tutorial on Meshing Point Clouds using MeshLab.

As for representing your point cloud the easiest format to use is the XYZ format:

X1 Y1 Z1
X2 Y2 Z2
etc.

Another good format that is relatively easy to use is Object (OBJ) model format.
